Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.
Yes, some cells are terminally differentiated and are no longer capable of dividing. These include mature nerve cells and muscle cells. However, most cells in the body, such as skin cells and blood cells, are capable of division.
The primary factory for producing blood cells is the bone marrow, which is found in the cavities of bones. It is responsible for producing red blood cells, white blood cells, and platelets through a process called hematopoiesis.
Meiosis would produce sperm cells and epithelial cells in plants. Red blood cells do not undergo meiosis, as they lack a nucleus and are not capable of dividing.
The stratum basale (basal layer) of the epidermis contains the only cells capable of dividing through mitosis. These cells are known as basal cells or basal keratinocytes and are responsible for replenishing the outer layers of the epidermis.
Blood cells.
Blood cells (Steam cells) start producing new red blood cells and white blood cells.
White blood cells
The bone marrow is the primary organ responsible for producing all types of blood cells, including red blood cells, white blood cells, and platelets. It is located within the cavities of bones.
The fastest dividing human cells are usually found in the bone marrow, where hematopoietic stem cells continuously produce new blood cells. These cells undergo rapid and constant division to replenish the body's supply of red blood cells, white blood cells, and platelets.
Cells in the skin, hair follicles, and cells that line the digestive tract are constantly dividing in the human body to maintain these tissues. Additionally, cells in the bone marrow, responsible for producing blood cells, also undergo frequent division.
White blood cells
The cells capable of fighting bacterial infection in the body are white blood cells, specifically neutrophils and macrophages. These cells work together to engulf and destroy bacteria using mechanisms such as phagocytosis and releasing antimicrobial substances.
